SAP-SPOUT.

SPECIFICATION forming part of Letters Patent No. 436,557, dated September 16, 1890.

Application filed January 13, 1890. Serial No. 336,727. (No model.)

To all whom it may concern.-

Be it known that I, HARRY BLAKE, acitizen of the United States, residing at Perrysburg, in the county of Oattaraugus, State of New York, have invented certain new and useful Improvements in Sap-spouts, of which the.

. thereof.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be specifically pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which Figure 1 is a central vertical longitudinal section through my improved sap-spout. Fig. 2 is a cross-section on the line as 00 of Fig. 1. Fig. 3 is an end view looking in the direction of the arrow in Fig. 1. Fig. 4: is a perspective view of the sleeve part of the suspendinghook.

Like letters of reference indicate like parts throughout the several views.

Referring now to the details of the drawings by letter, A designates the body portion of the spout, comprising in a single element the driving-plug A, preferably flanged or formed into the shape shown in Fig. 3 to aid in the entrance of the same into the tree, the driving-head A the apertured neck A and the spout A.

Surrounding the driving-plug may be an annular cuttingring A formed integral with the driving-head A (shown bydotted lines in Fig. 1,) having a sharpened entering-edge and forming an annular sap-chamber A, from the lower portion of which there is an opening a, which communicates through the neck withthe spout, as shown clearly in Fig. 1. It will be observed that this neck portion joins the driving-head at the extreme lower portion thereof, so as not to interfere with the ready driving of the device into the tree.

larged from the sap-chamber outward, as shown in Fig. 1, so as to prevent choking of the mouth of the same and affording ready outlet for all the sap. The under side of this neck portion is enlarged, as shown at b, to strengthen the same, and this enlarged portion is formed with a shoulderc upon its under side, for a purpose which will soon appear. This enlargement serves to strengthen the device at the junction of the spout or neck and the main body of the device, and also provides for the forming of the shoulder without weakening the parts, and also provides for the formation of the enlarged opening through the neck. The neck is slightly tapered from its junction with the body outward.

B is the suspendinghook provided-with a sleeve B, the bore of which is slightly tapered to conform to the taper of the neck of the spout. This sleeve B is enlarged diametrically, as shown at B In practice the hook is removed from the neck of the spout and the body portion driven into the tree by means of a hammer or other suitable instrument brought into contact with the driving-head. The device is driven into the tree till the sharpened edge of theannular cutting-ring cuts through the bark and beds itself into the solid wood, thus cutting off the bark-sap or any other substance which might come from the new grain of timber being formed between the bark and the solid wood. I thus get rid of the bark-sap, which is bitter, and the so-callec sugar-sand, which comes from between the bark and the solid wood. The solid neck passing through the bark into the solid wood permits the spout to take nothing but the sap from the solid wood. After the body portion has been driven into the tree the sleeve of the hook is placed over the spout and over the neck with the hook upward, as indicated by dotted lines in Fig. 1, the diametrical enlargement of the sleeve being at the under side. The sleeve, after being pushed up against the driving-head, is rotated on the neck until it is brought into the position in which it is shown by full lines in Figs. 1 and 2, the enlargement of the sleeve coming on top of the neck, as shown in Fig. 2. This prevents displacement of the sleeve until the hook is reversed or thrown upwardinto the position in which it is shown by dotted lines in Fig. 1,so that the enlargement of the sleeve will come coincident with the shoulder on the under side of the neck, permitting the Withdrawal of the sleeve.

The annular sap-chamber may sometimes be omitted without affecting the other features of the device, and this latter construction is indicated by full lines in Fig. 1.

The shoulder d, formed by the enlargement of the neck, provides a hold for a claw or other device by which the spout may be withdrawn from the tree.

The passage through the neck and the outer face of the annular sap-chamber incline in opposite directions, as shown clearly in Fig. 1, which is considered important, inasmuch as it provides for the draining of the sap, preventing it from freezing in cold weather, and avoiding souring of the samein warm weather.

What Iclaim as new is- 1. A sap-spoutcomprising a body portion and integral neck, a driving-head, and a spout having passage through the driving-head and neck, with an enlargement at the junction of the neck and body, the body being formed With a shoulder, and a supporting-hook carrying a sleeve rotatable on the body portion and formed with a diametrical enlargement, substantially as specified.

2. A sap-spout comprising a body portion having formed integral therewith an annular cutting-ring, a neck, a driving-head, and a spout having communication with the space inclose'd by the cutting-ring through the neck, and an enlargement at the junction of the neck and body, the passages through the neck and sap-chamber inclining in opposite directions, combined with a hook carrying a sleeve rotatable on the body portion and formed with a diametrical enlargement, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

HARRY BLAKE.
